(subclass FlightControlSurfaces Device)	Transportation.kif 3348-3348	Flight control surface is a subclass of device
(documentation FlightControlSurfaces EnglishLanguage "Flight control surfaces are aerodynamic devices allowing a pilot to adjust and control the aircraft's flight attitude.The primary function of these is to control the aircraft's movement along the three axes of rotation. A conventional fixed-wing aircraft uses three primary flight control surfaces – aileron, rudder and elevator to control the roll, yaw, and pitch respectively. Secondary flight control surfaces might include spoiler, flaps, and slats on the wings.[Wikipedia]")	Transportation.kif 3349-3355	Flight control surface is a subclass of device
